I saw a second hand computer shop selling 2nd hand PC's, Laptops, tables and chairs along Aurora blvd., Cubao (near A&S Lamps building / near Anonas-Aurora intersection) I'm not 100% sure that the shop is still there because the last time I saw it was over a year ago.

PC Options in Gilmore Ave cor. Aurora Blvd. has a lot of computer tables and chairs to choose from and they are very reasinably priced.

Go to HMR Philippines along Pioneer Street corner Reliance Street in Mandaluyong City. They sell factory close-outs, second hand stuff, and sometimes brand new stuff. They have a whole warehouse of stuff.
